When the Mud and Grass effect dries, it looks much too brown to have crushed grass, it doesn't simulate the grass juices coloring the mud like the given image shows, if you would like a greener effect you have the add in the green color that you want. And while it wasn't much effort to customize the coloring, I would've expected the picture to depict the browner color.

Just got the bottle and was testing to see how long it takes to dry. But when it did it dried glossy, I guess it would simulate being wet but I hate the glossy look of paint. Maybe I did not mix it well enough. Will test more before i apply to a model
